It measures 0.136 inches (Wire Size 29, 3.45 mm) in diameter with a straight-cylindrical shank and a 130-degree faceted drill point. Built from high speed steel with a coated finish, this bit is web-thinned with a tapered web configuration to reduce thrust and improve chip evacuation. The two-flute, regular spiral design delivers consistent cutting action in demanding production environments. Overall length is approximately 2.05 inches (52 mm), with a shank diameter of approximately 0.157 inches (4 mm) and a flute length of approximately 0.787 inches (20 mm).\u003c\/p\u003e\u003cp\u003eThis screw machine length bit is suited for close-tolerance drilling operations in steel, stainless steel, aluminum, aluminum alloy, and aluminum silicate workpieces. Its compact body length makes it ideal for drill press, CNC, and turret lathe setups where rigidity and minimal deflection are critical. The Series 1100 designation places it in OSG's high-performance drill line, making it a practical choice for production shops, tool rooms, and maintenance environments that require repeatable hole quality in ferrous and non-ferrous metals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire Size 29 diameter (0.136 inches \/ 3.45 mm) with a diameter tolerance of +0 to -0.018 mm for close-tolerance work\u003c\/li\u003e\n\u003cli\u003e130-degree faceted drill point reduces walking and improves entry accuracy on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web lowers cutting thrust and extends tool life in production drilling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with coated finish for improved wear resistance and heat dissipation\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body increases rigidity and minimizes deflection compared to jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, two-flute spiral design compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank drill chucks and collet systems accepting a 4 mm (approximately 0.157 inches) shank diameter.

Secure the shank fully in the chuck or collet before operation and verify spindle runout is within acceptable limits for the required hole tolerance. Always power down and de-energize the machine before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines when selecting feeds and speeds for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.1360 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 52 mm (approximately 2.05 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20 mm (approximately 0.787 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm (approximately 0.157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Aluminum, Aluminum Alloy, Aluminum Silicate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8595345\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747398648114,"sku":"8595345","price":37.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32dc54c8a37c94aaab7b2984d0991382.jpg?v=1788879450","url":"https:\/\/voomisupply.com\/products\/osg-8595345-screw-machine-drill-bit-0-136-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
